Our top spammer and scammer list is not just a static list — it's a live and always updating defense network at your disposal that uses both crowdsourced real-time insights and pattern recognition on calls.

Crowdsourced Real-Time Defense: Truecaller relies on its 450 million active users to report scams instantly. If a new "Tax Fraud" scam starts at 9:00 AM and the Truecaller community flags it by 9:05 AM, the number is burned for everyone else immediately.

Pattern Recognition: The AI looks for inhuman behavior, it constantly monitors calling trends and frequency across the global network. By spotting sudden spikes in suspicious activity or unusual calling patterns, Truecaller can proactively flag potential threats before they even reach your phone.

How do we stop a normal person from being marked as spam by a prankster?

• User Credibility: A few isolated reports from "trolls" won't ruin a number’s reputation. Our algorithms require reports from a wide, diverse community to trigger a spam label.
• Dynamic Correction: If a legitimate number gets wrongly flagged, the owner can request a review. Also, if users start tapping "Not Spam" on a flagged number, our AI quickly re-evaluates and removes the red label if it finds it as a legitimate request.
